Fun part was that CIA was focused mainly on espionage purpose while the BND was mainly focused on earning money they can spend without supervision for other secret projects.
We don't know, but we do know that during the investigation into it when it became publicly know a complain from the CIA surfaced that the BND acted to profit orientated. Through I would have to look up the exact details tbh. Just something which I found kinda amusing when I stumbled over it.
